The main factors to consider are: material of the pipe joint (e.g. plastic or metal), thread size, required resistance to temperature or media.
The cure speed varies from product to product and also depends on the following: thread material, temperature, gap size. See technical data sheets for more info.
Liquid silicone-based thread sealants are the best for plastic joints. In plumbing, LOCTITE 55 sealing cord is an alternative option.
In dimensionally stable threaded assemblies, anaerobic products can be used at up to 1,000 bar.
Activator accelerate the cure of anaerobic products and are recommended for: bonding at below 5°C and applications on inactive materials (e.g. stainless steel and aluminium, chromated or zinc-alloyed surfaces).
